3 Claims.

This invention relates to an improvement in detachable sole or last plates as used in connection with shoe presses for attaching soles to shoes by the cement process and particularly to a device which makes possible the use of numerous last plates or sole plates with one and the same last body.

In the attachment of soles to shoes by the cement process, it is essential that the soles should be pressed up against the bottom of the shoes with an even pressure at all points thereby insuring that all parts of the sole will be attached to the shoe bottom by cement. Due to the large variety of sizes of shoes, as well as due to the variety of shapes, shape of shoe bottoms, etc., it is commonly required that a large number of lasts be available to be able to handle all kinds of shoes. The solid cast iron lasts, as formerly used, were heavy and cumbersome and required a considerable space for storage. To avoid these disadvantages, the present invention attains the following objects:

One object of my invention is to provide a last with an interchangeable sole plate whereby the same last body can be used with numerous sole plates.

Another object of this invention is to provide a simple and easy method of attaching the sole plate to the last body.

Still another object of this invention is to provide a last assembly which is easily manufactured and low in cost.

An object ancillary to the above is to provide a last assembly for shoe presses which will permit the use of a considerable number of' sole plates with one last body, thereby reducing the size and weight of the total number of lasts required and permitting easy storage of same.

Other objects and advantages of my invention will be apparentduring the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals .are employed to designate like parts throughout the same,

Figure l is a front elevation of the shoe press with one last in place,

Figure 2 is a plan View along line 2-2 in Figure 1,

Figure 3 is a side elevation and partial crosssection of the shoe press with last in place,

Figure 4 is a plan view of last body with sole plate, and

Figure 5 is a side elevation of same with a cross-section through a sole plate.

' of the shoe press.

. may be used upon either of screws I3 and I4.

The base I 0 has two sole shaped recesses wherein are placed sponge rubber pads I6 and I I, whereupon the soles are placed when same are to be attached to shoes. At the rear end of the sponge rubber pads I6 and I! are placed spacers I8 which serve to lift the pads I6 and I! to make same conform closer to the form of the shoe such as may be required in the case of ladies shoes, etc.

The last consists of a sole plate I9 and the last body 29. The latter part is in' the shape of a U and serves to transmit the pressure from the pressure screws I3 and I I to the last plate or sole plate I9. The last body 29, as may be seen in Figures 4 and 5, has a nose 2| which fits under spring 22 of the last plate I9 and is held in position by same. The part 20 also has a flange-like extension 23 on either side of nose 2I. The flanges 23 fit into recesses provided by guide members 24 and 25 of the last plate I9, and projecting parts 26 and 2! of the said flanges 23 provide a stop against members 28 and 29 of the sole plate I9. The spring 22 is preferably fastened to the sole plate I9 by a screw 30, and the position of the spring 22 between guide members 24 and 25 prevents a side-way motion of spring 22.

The operation of my invention is as follows:

In the processes of cementing soles on shoes, the usual method is followed and a sole plate I9 of suitable size for the particular shoe is selected and quickly fastened to the last body 20 by the insertion of nose 2I of same under spring 22 while simultaneously the flanges 23 are held in the recess formed by the guide members 24 and 25. The last body 29 is pushed forward against the sole plate I9 until the stop flanges 26 and 21 hit stop members 28 and 29. The spring 22 will, at this point, have reached the groove behind nose 2| of the last body 20 and will hold the last plate I9 securely to the last body 29. The complete last is then inserted in the shoe and applied in the press in the usual manner.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention I claim:

1. In a shoe press of the character described the combination of a base, said base having two sole-shaped recesses; a pair of thick, rubber pads fitted into said recesses; a plurality of spacer members adapted for insertion in said base and said rubber pads; a pair of pillars fastened in said base; a yoke supported by said pillars; a pair of press screws located centrally over each of said recesses in said base and rotatable in said yoke; a hand wheel adaptable for use with either of said screws; a last member having a p U shaped body adaptable for insertion between 2. A last assembly for shoe presses having in combination a U shaped last body, said last body having a flange-like rib on both sides of its base and a nose-shaped forward extremity of said base; a sole plate; a pair of guide members on said sole plate adaptable for fitting over said flange-like ribs of said last body, and a spring catch engageable over said nose-shaped forward extremity of said last body.

3. A last assembly for shoe presses having in combination a U shaped last body, said last body having a flange-like rib on both sides of its base and a nose-shaped forward extremity of said base; a sole plate having a recess with stop and guide elements suitable for holding the base of said last body, and a spring catch fastened to said sole plate and adaptable for holding said nose-shaped forward extremity of said last body in said recess.
